Автоматическое обновление APK Android API 30: java.lang.IllegalArgumentException: не удалось найти настроенный корень, с ⇐ JAVA

[Anonymous]

Я пытаюсь автоматически обновить приложение Android с помощью URL-адреса, но получаю сообщение об ошибке: java.lang.IllegalArgumentException: не удалось найти настроенный корень, содержащий /file:/storage/emulated/0/Download
Я следую этому ответу FileProvider — IllegalArgumentException: не удалось найти настроенный корень, но ошибка все еще здесь.
Я использую Java android с SDK 30
